Question Answering with YouTube Videos Using RAG in LangChain 3 Weeks Ago by usmanmalik57 In previous articles, I explained how to use natural language to interact with [PDF documents](https://www.daniweb.com/programming/computer-science/tutorials/541732/paris-olympics-ticket-information-chatbot-with-memory-using-langchain) and [SQL databases](https://www.daniweb.com/programming/computer-science/tutorials/541771/using-natural-language-… Retrieval Augmented Generation with Hugging Face Models in LangChain 2 Weeks Ago by usmanmalik57 In my [previous articles](https://www.daniweb.com/programming/computer-science/tutorials/541732/paris-olympics-ticket-information-chatbot-with-memory-using-langchain), I explained how to develop customized chatbots using Retrieval Augmented Generation (RAG) approach in [LangChain](https://www.langchain.com/). However, I used proprietary models such… Retrieval Augmented Generation (RAG) with Google Gemma From HuggingFace 2 Months Ago by usmanmalik57 In a previous article, I explained [how to fine-tune Google's Gemma model for text classification](https://www.daniweb.com/programming/computer-science/tutorials/541544/fine-tuning-google-gemma-model-for-text-classification-in-python). In this article, I will explain how you can improve performance of a pretrained large language model (LLM) using … Paris Olympics Chatbot- Get Ticket Information Using Chat-GPT and LangChain 1 Month Ago by usmanmalik57 I was searching for Paris Olympics ticket prices for tennis games recently. The official website directs you to a [PDF document](https://tickets.paris2024.org/obj/media/FR-Paris2024/ticket-prices.pdf) containing ticket prices and venues for all the games. However, I found the PDF document to be very hard to navigate. To make things easier, I … Paris Olympics Ticket Information Chatbot with Memory Using LangChain 1 Month Ago by usmanmalik57 In my previous article, I explained how I developed a simple chatbot using LangChain and Chat-GPT that can answer queries related to Paris Olympics ticket prices. However, one major drawback with that chatbot is that it can only generate a single response based on user queries. It can not answer follow-up questions. In short, the chatbot has no … Re: Trying to animate sprite using DirectX9 1 Month Ago by Pavel_11 Hello, it is unneccessarily to use right movex or leftmovex , because it is to much variables.

It creates a [i]vector <int>[/i] and assigns it the values 0 - 51. Then it shuffles these values and prints it to the screen. When I compile it, I get no errors, but when it runs, it throws an error on Windows and it quits the console window and tells me that it has encountered an … Re: Vector help please 14 Years Ago by Nick Evan You're still using array, when you should be using vectors. Here's how I'd do it: [code=cplusplus] void ShowInv(vector<string> inv){ cout << "Your inventory:\n"; for (unsigned int i = 0; i < inv.size(); i++) cout << inv.at(i) << endl; } int main() { vector<string> inventory; … Re: Vector help please 14 Years Ago by Nick Evan [QUOTE=gangsta gama;928698]i still dont know what [icode]cout << inv.at(i) << endl;[/icode] means :). I get the variable: inv. I just dont get the at(i) part. [/quote] It's means the i-th object in the vector. In other words: If you say [icode]inv.at(i)[/icode] you get the left most book on the shelf.

I eliminated the possibility of rand() duplicating cards in the deck by erasing each index rand() selected from the deck. The range for rand() each time is changed because it gets the new size of the deck (after the previous rindex was erased). At the end, the deck vector is assigned the value … Re: Vector help please 14 Years Ago by VernonDozier [QUOTE=gangsta gama;927720]Hello all, I have been programing for a year or two and i dont get vectors.

Thank you very much, Gangsta gama[/QUOTE] … Re: Vector Help 15 Years Ago by Ancient Dragon lines 13 and 14: the size of the vectors is 0 because you have not assigned any elements to the vectors. Therefore the loop starting on line 17 will never execute because both s and decksize are 0. similar lines 31 and 32 cause program to crash because deck does not have a size. How to fix: before line 31 assign a size: [icode]deck.… Re: Vector Help 15 Years Ago by shadwickman Oh! Wow that was a stupid mistake. I didn't realize I had been trying to use [icode]deck[ i ] = i;[/icode] on the vector without a length specified. Another option would be to replace line 32 with [icode]deck.push_back( i );[/icode], right? (I'm new to how vectors work in C++, obviously :P) Re: Vector Help 15 Years Ago by Lerner Works for me too. I keep getting the same shuffle of the deck because I didn't seed the random number generator before calling rand(), but I have had no problems with erasure of element from vector using either VC6++ or VC8Express.
